Is it common practice for a counselor to ask leading questions?

Perhaps you can help: If you find counseling helpful except for this, you might be able to fix this. Say that it seems like this is happening and that you'd prefer a different approach. You might start a good conversation and hear encouragement to talk more freely on your own about things important to you. Also, you can find another if this is not a good fit. Working well together is important and this might be a start.

Psychotherapy: Questions are generally related to the topics you have introduced, leading questions are not atypical but should be related to your goals. Best.
